The coastal prickly pear is a native of northern Baja California and southern California.
It is a common sight in the Laguna Beach area.

Identification: These cacti are low 12-24" (30-60 cm) and shrublike,
and have some long, rigid spines,
as well as short, hairlike spines called glochids. It is the short ones, which detach easily, that can be painful and
difficult to remove. Stem segments are roughly oval in shape, 2½-12" (7-30 cm) × 1¾-4" (5-10 cm). Flowers are yellow or orange-yellow, sometimes with some red, sometimes red or shades of purple.
